STANDARD TERMS AND CONDITIONS FOR
RESTRICTED STOCK UNITS
(Part A Awards)

These Standard Terms and Conditions apply to the Award of restricted stock units granted pursuant to the Zayo Group Holdings, Inc. 2014 Stock Incentive Plan (the “Plan”), which are evidenced by a Grant Notice or an action of the Committee that specifically refers to these Standard Terms and Conditions and are designated as “Part A Awards”.  In addition to these Standard Terms and Conditions, the restricted stock units shall be subject to the terms of the Plan, which are incorporated into these Standard Terms and Conditions by this reference.  Capitalized terms not otherwise defined herein shall have the meaning set forth in the Plan.

1.TERMS OF RESTRICTED STOCK UNITS

Zayo Group Holdings, Inc. (the “Company”), has granted to the Participant named in the Grant Notice provided to said Participant herewith (the “Grant Notice”) an award of a number of restricted stock units (the “Award” or the “Restricted Stock Units”) with each Restricted Stock Unit representing the right to receive one share of the Company’s common stock, par value $0.001 (the “Common Stock”) specified in the Grant Notice.  The Award is subject to the conditions set forth in the Grant Notice, these Standard Terms and Conditions, and the Plan, each as amended from time to time.  For purposes of these Standard Terms and Conditions and the Grant Notice, any reference to the Company shall include a reference to any Subsidiary.

2.VESTING AND FORFEITURE OF RESTRICTED STOCK UNITS

The Award shall not be vested as of the Grant Date set forth in the Grant Notice and shall be forfeitable unless and until otherwise vested pursuant to the terms of the Grant Notice and these Standard Terms and Conditions.  After the Grant Date, subject to termination or acceleration as provided in these Standard Terms and Conditions and the Plan, the Award shall become vested as described in the Grant Notice with respect to that number of Restricted Stock Units as set forth in the Grant Notice.  Restricted Stock Units that have vested and are no longer subject to forfeiture are referred to herein as “Vested RSUs.”  

Notwithstanding anything contained in these Standard Terms and Conditions to the contrary, upon a Participant’s Termination of Employment prior to the Vesting Date set forth in the Grant Notice for any reason, the Award and all of the Restricted Stock Units subject thereto shall be forfeited and canceled as of the date of such Termination of Employment.

3.SETTLEMENT OF RESTRICTED STOCK UNITS

Each Vested RSU will be settled by the delivery of one share of Common Stock (subject to adjustment under Section 14 of the Plan) to the Participant or, in the event of the Participant’s death, to the Participant’s estate, heir or beneficiary, promptly following the Vesting Date (but in no event later than 30 days following the Vesting Date); provided that the Participant has satisfied all of the tax withholding obligations described in Section 6 below, and that the Participant has completed, signed and returned any documents and taken any additional action that the Company deems appropriate to enable it to accomplish the delivery of the shares of

Common Stock.  The date upon which shares of Common Stock are to be issued under this Section 3 is referred to as the “Settlement Date.”  The issuance of the shares of Common Stock hereunder may be effected by the issuance of a stock certificate, recording shares on the stock records of the Company or by crediting shares in an account established on the Participant’s behalf with a brokerage firm or other custodian, in each case as determined by the Company.  Fractional shares will not be issued pursuant to the Award.  

Notwithstanding the above, (i) the Company shall not be obligated to deliver any shares of the Common Stock during any period when the Company determines that the delivery of shares hereunder would violate any federal, state or other applicable laws, (ii) the Company may issue shares of Common Stock hereunder subject to any restrictive legends that, as determined by the Company’s counsel, are necessary to comply with securities or other regulatory requirements, and (iii) the date on which shares are issued hereunder may include a delay (which delay shall in no event extend beyond 30 days following the Vesting Date) in order to provide the Company such time as it determines appropriate to address tax withholding and other administrative matters.  

4.RIGHTS AS STOCKHOLDER

Participant shall not be, nor have any of the rights or privileges of, a stockholder of the Company in respect of any RSUs unless and until shares of Common Stock settled for such RSUs shall have been issued by the Company to Participant (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company).  

Notwithstanding the foregoing, from and after the Grant Date and until the earlier of (a) the time when the Restricted Stock Units become vested and payable in accordance with the terms hereof or (b) the time when the Participant’s right to receive Common Stock upon payment of Restricted Stock Units is forfeited, on the date that the Company pays a cash dividend (if any) to holders of Common Stock generally, the Participant shall be entitled to a number of additional whole Restricted Stock Units determined by dividing (i) the product of (A) the dollar amount of the cash dividend paid per share of Common Stock on such date and (B) the total number of Restricted Stock Units (including Dividend Equivalents paid thereon) previously credited to the Participant as of such date, by (ii) the Fair Market Value per share of Common Stock on such date.  Such Dividend Equivalents (if any) shall be subject to the same terms and conditions and shall be settled or forfeited in the same manner and at the same time as the Restricted Stock Units to which the Dividend Equivalents were credited.

5.RESTRICTIONS ON RESALES OF SHARES

The Company may impose such restrictions, conditions or limitations as it determines appropriate as to the timing and manner of any resales by the Participant or other subsequent transfers by the Participant of any shares of Common Stock issued pursuant to Vested RSUs, including without limitation (a) restrictions under an insider trading policy, (b) restrictions designed to delay and/or coordinate the timing and manner of sales by Participant and other holders and (c) restrictions as to the use of a specified brokerage firm for such resales or other transfers.

6.TAX WITHHOLDING

The Company has the right to deduct or otherwise effect a withholding of the amount of any taxes (including, but not limited to, any FICA, FUTA, and similar taxes) required by federal, state, local or foreign laws to be withheld or otherwise deducted and paid with respect to the grant, vesting or settlement of the Restricted Stock Units; or, in lieu of such withholding, to require that the Grantee pay to the Company in cash (or, at the sole discretion of the Committee, in the form of shares of Common Stock or net settlement of the Award) the amount of any taxes required to be withheld or otherwise deducted and paid by the Company or any Subsidiary in connection with the grant, vesting or settlement of the Restricted Stock Units.  Unless the tax withholding obligations of the Company or any affiliate are satisfied, the Company will have no obligation to issue a certificate for any of the shares of Common Stock otherwise issuable pursuant to the Award (whether vested or unvested).

7.NON-TRANSFERABILITY OF AWARD

The Participant understands, acknowledges and agrees that, except as otherwise provided in the Plan or as permitted by the Committee, the Award may not be sold, assigned, transferred, pledged or otherwise directly or indirectly encumbered or disposed of other than by will or the laws of descent and distribution.  

8.NON-COMPETE; NON-SOLICIT

The Participant hereby agrees that during Participant’s service with the Company and for a period of one year after Participant’s Termination of Employment (the “Restricted Period”), Participant will not directly or indirectly engage or participate in (whether as an employee, consultant, proprietor, partner, director or otherwise) any position (i) of a business development/mergers and acquisitions nature, with any person, firm, corporation or business that engages in owning or operating fiber networks in the United States or other area or region in which the Company or any Subsidiary or Affiliate conducts business, or (ii) of a sales, sales management, sales engineering, marketing, product or network development nature, or any senior management level position,  if such position involves, directly or indirectly, products or services similar to the Company’s being sold to one or more of the Company’s top 200 customers at any time during the period between the Grant Date and the date on which a violation of this Section 8 occurs (a current list of such top 200 customers as of the Grant Date of this Award is attached hereto as Exhibit A), or (iii) any business in an area or region in which the Company or any Subsidiary or Affiliate conducts business as of the date the event occurs which is directly in competition with a business then conducted by the Company or a Subsidiary or Affiliate.  In addition, during the Restricted Period, Participant will not (x) induce any customer or supplier of the Company or a Subsidiary or Affiliate, with which the Company or a Subsidiary or Affiliate has a business relationship, to curtail, cancel, not renew, or not continue his or her or its business with the Company or any Subsidiary or Affiliate, or (y) induce, or attempt to influence, any employee of or service provider to the Company or a Subsidiary or Affiliate to terminate such employment or service, or (z) interfere with or harm, or attempt to interfere with or harm, the relationship of the Company or any Subsidiary or Affiliate with any person who at any time was a customer or supplier of the Company or any Subsidiary or Affiliate or otherwise had a business relationship with the Company or any Subsidiary or Affiliate or hire, solicit for

hire or cause to be hired, either as an employee, contractor or consultant, any person who is currently employed, or was employed at any time during the six-month period prior thereto, as an employee, contractor or consultant of the Company or any Subsidiary or Affiliate.  Notwithstanding the foregoing, this Section 8 shall not apply (i) in any case where the Participant’s Termination of Employment by the Company was not for Cause or (ii) at any time after expiration of the Restricted Period.  For avoidance of doubt, this Section 8 will apply in any case where the Participant voluntarily terminates service with the Company or where the Participant experiences a Termination of Employment with Cause.  In the event that Participant violates the terms of this Section 8, the Company shall provide Participant with written notice of such violation and all of Participant’s Restricted Stock Units hereunder, including Vested RSUs, to the extent then outstanding, will be automatically, and without any further action on the part of the Company, forfeited as of the date of such written notice from Company.

9.WAIVER OF CLAIMS

By executing the Grant Notice, Participant hereby releases and discharges Company, its directors, officers, employees, agents or successors of and from any demands or claims, of whatever kind or nature, whether known or unknown, arising out of Participant’s employment or other service with Company, including, but not limited to, claims of breach of express or implied contract, promissory estoppel, detrimental reliance, infliction of emotional distress, harassment and/or hostile work environment, claims under the Employee Retirement Income Security Act of 1974 or the Family and Medical Leave Act of 1993, the WARN Act, or claims of discrimination under the Title VII of the Civil Rights Act of 1964, as amended, the Age Discrimination in Employment Act of 1967, as amended, the Americans with Disabilities Act of 1990, the Sarbanes Oxley Act of 2002, the Internal Revenue Code, New York Anti-Discrimination Act, or any other local, state or federal law or regulation, as of the Grant Date.

10.OTHER AGREEMENTS SUPERSEDED

The Grant Notice, these Standard Terms and Conditions and the Plan constitute the entire understanding between the Participant and the Company regarding the Award.  Any prior agreements, commitments or negotiations concerning the Award are superseded.

Neither the Participant (individually or as a member of a group) nor any beneficiary or other person claiming under or through the Participant shall have any right, title, interest, or privilege in or to any shares of Common Stock allocated or reserved for the purpose of the Plan or subject to the Grant Notice or these Standard Terms and Conditions except as to such shares of Common Stock, if any, as shall have been issued to such person in connection with the Award.  Nothing in the Plan, in the Grant Notice, these Standard Terms and Conditions or any other instrument executed pursuant to the Plan shall confer upon the Participant any right to continue in the Company’s employ or service nor limit in any way the Company’s right to terminate the Participant’s employment at any time for any reason.

Notwithstanding any other provision of the Plan or these Standard Terms and Conditions, this Award is not intended to provide for a deferral of compensation within the meaning of Section 409A of the Code and is intended to qualify for as a “short-term deferral” under Section 409A of the Code, and these Standard Terms and Conditions shall be construed or deemed to be amended as necessary to effect such intent.  Under no circumstances, however, shall the Company have any liability under the Plan or these Standard Terms and Conditions for any taxes, penalties or interest due on amounts paid or payable pursuant to the Plan or these Standard Terms and Conditions, including any taxes, penalties or interest imposed under Section 409A of the Code.
